Shin’Daal Backstory: The Shin’Daal is a race of extra-galactic travelers who came to this galaxy from their own, which was being ripped apart from massive black holes. They took all their combined intelligence and ship building skills to create a huge armada of worldships to escape their galaxy. They opened their jumpdrives but were too close to the black hole. The gravitational pull wreaked havoc with the drives and the navigators tried to change the route, but it caused a major malfunction with the drives. Thrown clear of their galaxy, the fleet was scattered to our galaxy and they arrived, damaged and battered in the Tingle Arm. They spent the next 2 decades moving through the arm and repairing their ships. They arrived in the Corporate Sector just after the Vong Invasion. Silently, they took over colonies and primitive planets, establishing staging points for their fleets and communication hubs. They spent this time, creating new ships from raw materials and designing new weapons and tools. During this time, they were able to capture many ships and download their information into their central hub. From this information, they learned about the Old Republic, the Galactic Empire, the civil war, Jedi and Sith. They sat back, biding their time until they were ready to make their move.
It helped that the Corporate Sector was isolated from the rest of the galaxy and that the major factions were more concerned with rebuilding their own territories. During that time the Shin’Daal attacked. In most cases, the planetary government didn’t know they were being invaded until it was too late. Some of the takeovers were bloody and some were welcomed at a change for the better from the Corporate Sector Authority.
The Shin’Daal invasion in the most part was completely different from the Vong Invasion. Instead of destroying all the cultures of the planets they took, the Shin’Daal worked to retain those cultures and traditions, adding their own on top of that. They also set up a loose coalition so that the planets could rule their daily lives and the Shin’Daal controlled the Sectors.
The last battle was taking over the CSA Capital on Etti IV. By that time, the CSA had lost most of their ships, either destroyed or turned over to the Shin’Daal. Facing annihilation, they surrendered and were exiled to a prison ship until they could be turned back into helpful citizens.
All of this, for the most part, went unnoticed by the Imperial Remnant and the Galactic Alliance. Now, having secured the Corporate Sector, the Shin’Daal closed off the sector and have most of their fleets patrolling the few hyperspace paths that lead into their territory.
